    On Android the setting is within the Signal app, so I assume it won’t leave the app and therefore won’t enter the notification system.

      Correct - the notification API from the server is literally just a ping to inform it there’s something to fetch. The app itself fills the notification content. If you tell it to leave it blank there’s nothing cached outside the application storage.

      Apps *can* let the server fill the entire notification content without waking the app, but that’s not how Signal works

        Play Store version uses Google’s push/FCM but yeah even then it’s just the generic ping data they get as I understand it. Some may not even want them to have timestamps, so there’s solutions to that:

        Can take it a step further grabbing the non-google APK on their website instead or using the hardened Signal fork named Molly. Both use a persistent WebSocket connection to Signal’s servers instead.
